The Siemens SENTRON 3VA2163-6HL32-0HC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at ambient temperatures up to 50 °C without derating — it holds the full 63 A from 40 °C through 50 °C, then steps down to 60.6 A at 55 °C and 53.6 A at 70 °C. The interrupting capacity runs from 242 kA at 240 V down to 5 kA at 690 V — the 242 kA figure at 240 V covers high-fault industrial services, while the 187 kA at 415 V and 440 V handles the common European low-voltage distribution levels. At 690 V the 5 kA rating still clears typical motor-circuit faults, but the breaker is sized for the 400 V class distribution panels it was designed around. The overcurrent release is an ETU320 electronic trip unit, which provides adjustable long-time, short-time, and instantaneous protection — the ETU320 is the standard electronic release for this 3VA2 frame, giving selectivity coordination in a downstream panel without relying on thermal bimetal drift.
Integrated auxiliary and shunt trip
The auxiliary trip module inside is order code 3VA9688-0BL30, and the basic switch assembly is 3VA2163-6HL32-0AA0 — both are replaceable sub-assemblies if a field repair is needed. No undervoltage release is fitted on this configuration, and no communication module or ground-fault monitoring is included — it is a line-protection breaker with shunt-trip remote capability, not a metering or communicating device.
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — the 105 mm width is the standard 3VA2 frame width for 3-pole units, so it fits the same DIN-rail or mounting-plate footprint as other 3VA2 breakers. Panel cutouts and bus-bar spacing designed for a 105 mm wide MCCB accept this unit without modification. Maximum power loss is 4 W, negligible for enclosure thermal calculations in a standard distribution panel.
For BOM planning, the 3VA2163-6HL32-0HC0 is specified into new designs and is a direct drop-in replacement for earlier 3VA2 frame breakers with the same 105 mm width and 63 A rating.
